map

1.   (mathematics)   function.

2.   (programming)   In functional programming, the most common higher-order function over lists. Map applies its first argument to each element of its second argument (a list) and returns the list of results.

 map :: (a -> b) -> [a] -> [b]  map f []     = []  map f (x:xs) = f x : map f xs 

This can be generalised to types other than lists.
